Several things here.. The mistake I see many groups make is that they have a tough new member program (or one that involves a lot of activity). After the member is initiated there is just weekly meetings to go to and parties...

Solution: Some kind of continuing education program. Sigma Nu actually has a program that can be given over 4 years. The main thing is that you don't let your older members feel disenfranchised and you keep your newer members in the loop about what's going on... why it's going on, etc.
